Catatan singkat Daily Life of Engineering Student tentang control loop di MATLAB. Berikut ini adalah script MATLAB untuk merancang controller berdasarkan kondisi loop yang diinginkan, loop shaping.
clear all, close all, clc;
%% The transfer function
P = tf([1],[1 0 2 5])
% the plant
% P =
% 1
% -------------
% s^3 + 2 s + 5
pole(P)
desiredLoop = tf([10],[1 0])
% desired loop
% 10
% --
% s
K = desiredLoop/P
% Gain
% K =

% 10 s^3 + 20 s + 50
% ------------------
% s
%% Closed-loop system
CL = feedback(series(K,P),1)
t = 0:0.01:5;
step(P,t), grid
hold on;
step(CL,t)
